Zusammenfassung:	There is provided a method of communicating vehicle data for vehicle control. The method includes (a) generating a multicast key and transmitting it to the vehicle in a multicast manner, (b) obtaining a hash key and an encryption key based on the multicast key and unique identification information of the vehicle, and (c) obtaining vehicle data by signal processing and combining first to n-th partition data of the vehicle data transmitted from the vehicle ("n" is an integer equal to or greater than 2). The i-th partition data includes i-th serial number information, an i-th MAC chaining value, i-th payload information, and an i-th MAC tag ("i" is an integer from 1 to n). The method further includes (c-1) receiving the i-th partition data, (c-2) authenticating the i-th partition data, and (c-3) decrypting the i-th payload information using the encryption key when the i-th partition data is authenticated.
